(Left) Mycelium phenotypes of the indicated strains grown on M2 medium. (Right) CG test of WT and the ΔPaMpk1 and ΔPaMpk2 mutants. Slices of the indicated strains were inoculated on M2 medium (M2) and M2 medium supplemented with yeast extract (M2 + YE). Parts of the inoculated slices corresponding to the growing edge are on the right; parts corresponding to the stationary phase area are on the left. The top of the slice corresponding to the aerial mycelium is oriented toward the top of the plate. Wild-type develops CG on M2 + YE (visible on the left of the culture as the pigmented area that lacks aerial hyphae) but not on M2 as previously described (Haedens et al. 2005), while the MAPK mutants never develop CG on either medium. Note the similar mycelium phenotypes of the ΔPaMpk1 and ΔPaMpk2 mutants.
